In a building in which an underfloor space is formed below the floor surface to be formed, a plurality of large bundles are erected from above the slab at an intermediate portion in the vertical direction of the pair of inverted beams arranged side by side at intervals. Without any bridge support, on top of these dramas, skip floors,
An article storage section is arranged side by side, and at the boundary between the skip floor and the article storage section, a drawer stored in the article storage section is opened at an entrance for drawing out on the skip floor, and the article storage section is opened. Of the plurality of supporting pulleys, at least the pulleys supporting the entrances and exits are a plurality of beam members arranged in parallel with each other, a connecting block sandwiched between opposing surfaces of adjacent beam members, and a plurality of beam members. And a connecting member that integrally connects the connecting block.According to such a feature, the noise from the article storage unit or the skip floor is not transmitted directly to the slab, and is passed downstairs through this slab. Without extending, and the squeeze can have sufficient rigidity without increasing its vertical width, and must be supported by the bundle on the slab. It is asserted against the load from the storage compartment, yet its Obiki is never reduce the effective volume of the underfloor space.

In order to achieve the above object, according to a second aspect of the present invention, in the first aspect, the upper surface of the opening of the skip floor can be opened and closed by a slidable movable floor. According to this feature, the skip floor can be easily changed to another room.
